Question

我有以下配置：

<int-http:outbound-gateway id="opgateway" request-channel="rallyUpdateRequest"
    url="https://rally1.rallydev.com/slm/webservice/v2.0/defect/9792864541?key={key}"
    http-method="POST" request-factory="rallyHttpRequestFactory"

    expected-response-type="java.lang.String"
    transfer-cookies="true"
    reply-channel="rallyUpdateResponse">
    <int-http:uri-variable
        name="key"
        expression="payload.secondArg" /> 
</int-http:outbound-gateway>

网关界面：

//@interface
public interface RallyUpdater {
    String updateDefect(@Payload String payload, @Header String key);
}

我有主要功能：

public static void main(String... args) throws Exception {
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(
                "context.xml");
....
        RallyUpdater updater = ctx.getBean("rallyUpdateGateway", RallyUpdater.class);
        String res=updater.updateDefect(defect,key);

        System.out.println("Response  ::::::::::"+res);

这引发了一个错误：

* **我需要将有效负载作为发布数据和URL中的密钥传递。

为什么在我们可以提供payload.secondArg时抛出错误？还有其他任何配置吗？

Answer 1

为什么不遵循StackTrace的建议？

updateDefect(@Payload String payload, @Header("key") String key);

从另一方面来看，我不清楚您将如何执行此操作payload.secondArg，因为您的有效负载为String。

对我来说配置应该是这样的：

<int-http:uri-variable name="key" expression="headers.key" />

否则您也应该显示<gateway>配置。
